Foldable computer with partially visible display when closed
Abstract
A portable computer has a base supporting a keyboard and a cover
with a display screen, with the cover being foldable away from the
base to an open configuration to view the entire screen and operate
the keyboard. The cover can also be folded flush against the base
to a closed configuration. A portion of the screen remains viewable
in the closed configuration, either by virtue of a window formed in
the base or by virtue of the portion of the cover extending past
the base.

Description
FIELD OF THE INVENTION
The present invention relates generally to portable computers that
can be folded open and closed.
BACKGROUND OF THE INVENTION
Portable computers such as the Thinkpad.RTM. have been provided
that conveniently afford computer access virtually anywhere a user
might want to bring the computer. Typically, to use the computer a
user opens it by folding a display panel away from a base that
contains a keyboard, hard disk drive, etc. When the computer is not
in use the display panel is folded back flush against the base both
to protect the keyboard and display and to provide a thin form
configuration that is convenient for carrying.
As recognized herein, it might be desirable to use the computer for
limited purposes (e.g., as a cell phone, as a music player) while
the user is moving, driving, or otherwise in a position that
renders opening up the computer infeasible or impractible. As
further understood herein, owing to the inability to see the
display when the computer is closed operating the computer
currently is not possible or is rendered excessively difficult
without opening the computer.
SUMMARY OF THE INVENTION
A portable computer includes a base supporting a key entry device
and a cover supporting a visual display screen. The cover is
foldably engaged with the base between an open configuration,
wherein the key entry device on the base is exposed for user
manipulation and the entire screen is exposed for viewing by a
user, and a closed configuration, wherein the cover is folded flush
against the base and a portion of the screen can be seen when the
computer is oriented with the base closest to a viewing person.
In one embodiment the base defines a periphery and is formed with a
window entirely inside the periphery. The portion of the screen is
viewable through the window when the computer is in the closed
configuration. A transparent pane that may be magnifying can be
disposed in the window. Alternatively, the portion of the screen is
viewable in the closed configuration by virtue of extending beyond
the periphery of the base.
In another aspect, a portable computer includes a base supporting
an input device and a cover supporting a screen. The cover is
pivotably engaged with the base between an open configuration,
wherein the input device on the base is exposed for user
manipulation and the entire screen is exposed for viewing by a
user, and a closed configuration, wherein the cover is folded flush
against the base. Means are provided for exposing a portion of the
screen for viewing when the computer is in the closed
configuration.
In still another aspect, a method for operating a computer includes
folding a cover having a screen flush against a base having an
input device to establish a closed configuration, and viewing a
portion of the screen past the base in the closed
configuration.
The details of the present invention, both as to its structure and
operation, can best be understood in reference to the accompanying
drawings, in which like reference numerals refer to like parts, and
in which:
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the present portable computer in
the open configuration, showing internal portions of the base in
phantom;
FIG. 2 is a perspective view of a first embodiment of the computer
in the closed configuration, in which a part of the display can be
seen through a window formed in the base;
FIG. 3 is a perspective view of a second embodiment of the computer
in the closed configuration, in which a part of the top edge of the
display extends beyond the base for viewing;
FIG. 4 is a perspective view of a third embodiment of the computer
in the closed configuration, in which a part of the side edge of
the display extends beyond the base for viewing; and
FIG. 5 is a perspective-view of a fourth embodiment of the computer
in the closed configuration, in which a window is formed in a
corner of the base so that part of the display behind the corner
can be seen.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring initially to FIG. 1, a portable computer is shown,
generally designated 10, that includes a base 12 and a cover 14
that can be pivotably moved relative to the base 12 about a hinge
16 or other folding/pivoting coupling mechanism. Specifically, the
cover 14 can be moved relative to the base 12 to the open
configuration shown in FIG. 1, in which a visual display screen 18
on the cover 14 can be seen in its entirety and in which an input
device or devices such as but not limited to a keyboard 20 and
joystick 22 on the base 14 are exposed so that a user can
manipulate them. Also, the cover can be folded to a closed
configuration shown in two different embodiments in FIGS. 2 and 3,
in which the cover 14 is flush against the base 12, substantially
covering the input devices of the base 12. The base 12 may also
include one or more disk drives 24 and a processor 26.
In accordance with the present invention, when the computer 10 is
in the closed configuration, a portion of the screen 16 can be seen
by a person when the computer is oriented with the base 12 closest
to a viewing person is shown in FIGS. 2-5. In the embodiment shown
in FIG. 2, this is accomplished by establishing a transparent
window entirely within the periphery of the base 12 as shown, so
that a portion 30 of the screen 14 (and data displayed thereon) may
be seen through the base 12. It is to be understood that the base
12 is configured such that no opaque components of the base
protrude into the window 28. The window 28 may be covered by a
plastic or glass pane 32 that can be clear and/or that can be
magnifying of the image on the exposed portion 30 of the screen.
Or, in the alternate embodiment shown in FIG. 3 a top (or bottom)
portion 34 of the screen may extend beyond the top (or bottom) of
the periphery of the base 12 when in the closed configuration, so
that a viewer can see the portion 34 by simply looking past the
base 12. Yet again, as shown in FIG. 4 a side portion 36 of the
screen may extend beyond the side of the periphery of the base 12
when in the closed configuration, so that a viewer can see the
portion 36 by simply looking past the base 12. As yet another
alternative, as shown in FIG. 5 a corner 38 of the base 12 may be
removed or may be rendered transparent so that a corner portion 40
of the screen can be seen when in the closed configuration.
In either case, it may now be appreciated that a user can close the
computer 10 and still see a portion of the screen, so that the
processor 26 can be controlled by means of, e.g., voice recognition
to maintain at least (and preferably only) the viewable portion of
the screen energized to display information related to, without
limitation, cell phone use, music playing, and similar applications
that can be executed on the computer 10.
While the particular FOLDABLE COMPUTER WITH PARTIALLY VISIBLE
DISPLAY WHEN CLOSED as herein shown and described in detail is
fully capable of attaining the above-described objects of the
invention, it is to be understood that it is the presently
preferred embodiment of the present invention and is thus
representative of the subject matter which is broadly contemplated
by the present invention, that the scope of the present invention
fully encompasses other embodiments which may become obvious to
those skilled in the art, and that the scope of the present
invention is accordingly to be limited by nothing other than the
appended claims, in which reference to an element in the singular
is not intended to mean "one and only one" unless explicitly so
stated, but rather "one or more". It is not necessary for a device
or method to address each and every problem sought to be solved by
the present invention, for it to be encompassed by the present
claims. Furthermore, no element, component, or method step in the
present disclosure is intended to be dedicated to the public
regardless of whether the element, component, or method step is
explicitly recited in the claims. Absent express definitions
herein, claim terms are to be given all ordinary and accustomed
meanings that are not irreconcilable with the present specification
and file history.
